Title: Labelling apparatus and method
IPC: B65C3/12
Filed: 1971-04-19
Abstract: 1342680 Labelling machine B & H MFG CO Inc 19 April 1971 [23 Jan 1970] 20309/71 Heading B8F In a labelling machine labels fed from roll L are cut by rotary cutter 286 and blade 290 and are then transported by a vacuum drum 314 to be applied, by their leading edges only, to containers held at the periphery of a rotating drum D. The labels are fed by driven roll 274 which may be controlled by a sensing head 272 detecting a mark as the label web passes over a plate 270. Slack is taken up by a dancing roller 408 on an arm 264 pivoted at 266. When roller 408 rises the link 406 is raised to lower driven roller 254<1> and thereby feed the web from the roll. Each label is glued as it passes from the cutter to the label applying position, the gluepot 390 being pivoted at 396 so as to be displaced away from the drum 314 by magnetic means 402 when a poor vacuum in the drum 314 denotes absence of a label. Likewise the stationary cutter blade 290 is pivotally mounted on arm 298 and may be moved by pneumatic piston 308 when a detector (not shown) fails to sense a, label, thereby avoiding excess wear. The vacuum drum 314 is indexable about axis 316 to adjust the label pick-up and discharge positions. Compressed air may be used to blow the label from the drum at the labelling station. The containers are received at R and then separated by screw S.R. Drum D comprises two axially spaced coaxial discs 120, 120a (Fig. 2) mounted on shaft 122, the containers being held against disc 121 by spring pressed clamps 128 pivoted at 126. The clamps are swung out of operative position at positions S1 and S2 (Fig. 1) by rails 136 adjustably mounted on the machine frame. Containers discharged at S2 are rolled by belt 420 so as to wrap the unadhered portion of the label round them. All parts of the apparatus are driven from a central drive shaft 438 (Fig. 2) which mounts the vacuum drum 314. In particular the label feed drum 274 is driven via variable speed drive pulleys 444 and clutch /brake 442. The variable speed drive is controlled by lever 446 and control of the rate of feed of the labels may be either manual or automatic in conjunction with reading head 272. The label roll L is mounted for rotation on shaft 202 and may be adjusted axially of the shaft by movement of sleeve 228 via lever 222 and screw 214. Provision is made to mount two rolls of labels.

Title: Improvements in or relating to valves
IPC: B64C13/00
Filed: 1951-08-29
Abstract: 702,354. Valves. NORTHROP AIRCRAFT, Inc. Aug. 29, 1951 [Jan. 8, 1951], No. 20411/51. Class 135 A valve comprises a valve spool with an axial extension protruding into an exhaust or return chamber in the valve body where it carries a reaction motor supplied with pressure fluid through an axial bore in the valve spool and the extension, and axial movement of the valve spool and extension is permitted by mounting the ends of the assembly in anti-friction bearings in rods extending out through pressure-retaining bearings in end caps to the valve body. As shown, the motor is rotated by reaction @ts issuing in opposite directions from two opposed hollow arms 62 carried on the axle of the valve spool 21. The latter comprises an axle with two lands 32 which control the flow of pressure fluid through series of ports 34 in a sleeve 25, these ports leading to grooves in the sleeve which communicate with outlets 17, 19 leading to the two ends of a jack. The ports in each series 34 are evenly spaced around the sleeve but are staggered in the axial direction, and, in the neutral position of the spool, there is negative lap between the lands and the pair of ports in each series spaced furthest apart. Pressure liquid is supplied to the space beween the lands through an inlet 11 and the exhaust takes place through outlet 12 from chambers in the casing at each end of the spool and sleeve, the two chambers being interconnected by four spaced bores 20. Escape of liquid from the various grooves of the spool is prevented by packing 120 and sealing rings 121. The pressure liquid also flows continuously into the hollow axle of the spool and from there into the arms '62 from which it escapes at right angles to the arms and so rotates the spool. The flow controlling action of the spool takes place when it is moved in the axial direction and, to enable this to be done, the ends of the spool rotate in ball bearings 39 in stirrups 40 having a pin and aperture connection 170 with reciprocatory rods 88, 111, the apertures in question being counterbored to prevent binding. A further pin 104 carried by the casing and working in a slot in the rod 111 limits the travel of the spool in the axial direction. Specifications 701,092 and 701,513 are referred to.

Title: Improvements in or relating to radar systems
Inventor: BRANDON PERCY SAMUEL
IPC: G01S13/58
Filed: 1948-08-04
Abstract: 680,705. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 21, 1949 [Aug. 4, 1948], No. 20624/48. Class 40 (vii). In a frequency - modulated radar system wherein beat notes are produced by heterodyning received echo signals with waves then being transmitted, means are provided for determining whether a target from which echo waves are being received is approaching or moving away from the radar system, by comparing the phases of the modulations produced, in respect of adjacent frequency components of the beat note, when the beat note is mixed with a signal comprising harmonics of the transmitter modulation frequency. It may be shown that the beat note produced from a stationary target comprises a plurality of integral-multiple harmonics of the transmitter modulation; however, when the target possesses radial motion these harmonic components are displaced and will thus heterodyne with harmonics of the transmitter modulation frequency. The manner in which the phases of successive heterodyne or modulation component vary with respect to one another is indicative of the direction of motion. In the application of the invention to a system employing symmetrical triangular modulation, the beat note led in on line W3 is mixed with pulse signals developed at PG in mixers M1, M2. The pulse signals developed in PG are synchronized with the commencement of the modulation cycle and it may be shown that in this case with symmetrical triangular modulation, the modulations of successive harmonic components of the pulse signal differ in phase by + 90 degrees, the sign of the difference being indicative of the direction of motion. Adjacent frequency components are selected by narrow band intermediate frequency amplifiers IFA1, IFA2, rectified at DT1, DT2, passed through filters DF1, DF2 and applied to phase discriminator PD which indicates the sense of the phase difference of the inputs thereto. A signal may also to be taken by a line W2 to apparatus for indicating the magnitude of the radial velocity. In the application of the invention to a system employing asymmetrical sawtooth modulation, the arrangement is similar to that already described; however, in this instance the pulse signal which is combined with the beat note is synchronized with an instant occurring a quarter of a period after the commencement of the transmitter modulation cycle. The pulse signal may be mixed as previously with the beat note or may alternatively be arranged to gate the channels carrying the two adjacent frequency components. As before the phases of the modulations produced differ by +90 degrees, the sense of the difference indicating direction of motion. Specifications 656,094 and 680,704 are referred to.

Abstract: 722,902. Time switches. NEWBERY S., and NEWBERY, Ltd., S. Feb. 6, 1953 [Nov. 6, 1951], No. 21052/51. Class 38 (5). A switch suitable for the controlling of sequential operations of a washing machine and embodying many of the features disclosed in Specification 568,732, comprises a number of horizontal time wires or rods 30 carried by an insulated frame 31 and divided into two independent zones 33 separated by a central zone 34. The wires 30 of the two zones 33 are relatively staggered so that the ends overlap in the zone 34 where they are successively wiped by contact blades 13 which move at a predetermined rate thereover. Each zone 33 may comprise sixty wires 30 and the contacts 13 may take one hour to traverse the zone 34 whereby the spacing between the adjacent wire ends in the zone 34 represents a half-minute interval. The frame 31 also carries a set of vertical circuit wires 35 arranged in a plane parallel to and spaced from the plane of the wires 30, the wires 35 being connectible to the several external control circuits, and connection between a wire 35 and the desired time wire 30 being made by a clip 37. The frame 31 comprises a panel B removably attached to one side of a support 1, the latter carrying resilient contact fingers 47 connected to the external control circuits and adapted to severally engage the wires 35 when the panel is in position. The contact blades 13 are positioned between insulating blocks 14 to form a resiliently-mounted head 12 carried by members 10 fixed to a chain 7 working on sprockets 3, 4. The spacing between the members 10 is such that as one blade 13 disengages the last wire 30 the following blade 13 engages the first wire 30. Electrical connection to the members 10 is made by a blade spring 11 the free end of which engages the chain 2. A motor 6 drives the chain 2 through sprockets 7, 8 and a chain 9.

Title: Improvements in or relating to photographic compositions and processes
IPC: G03C5/60
Filed: 1958-07-01
Abstract: 891,690. Photographic diazotype material. KALVAR CORPORATION. July 1, 1958 [July 2, 1957], No. 21104/58. Class 98(2). A composition comprises a diazonium compound, a vinyl monomer, and a thickening agent and a dried layer of this on a support may be imagewise exposed and then heated to give a visible image in the exposed areas. It is explained that the light-decomposition products of the diazonium compound react with remaining diazonium compound to give free radicals which latter initiate polymerization of the vinyl compound on heating to result in the image, and stated that removal of unexposed diazonium compound is not required. The layer may contain added decomposition products such as phenols, aminophenols or aromatic amines to produce polymer merely by heating, and this fact may be used to decrease the time of heat development after exposure or, with use of a small proportion of diazonium compound only, to produce reversed images. In Example I an aqueous solution containing gelatine, calcium acrylate and paradimethylaminobenzene diazonium-zinc chloride is poured on a glass slide, dried, exposed under a negative and heated to 75C. for one minute to give a white image. Example II is similar but uses other diazonium salts, Example III has acrylonitrile as monomer, polyvinyl alcohol as thickener, and produces an image on black paper, Example IV is for the reversal procedure referred to above and Example V uses an ethanol solution of nylon with methylmethacrylate and diazo compound on a cellulose acetate film. Numerous vinyl monomers, diazonium compounds and supports for the purpose are listed.

Title: Improvements in volatile anaesthetic vapourising apparatus
Inventor: EDMONDSON WILLIAM
IPC: A61M16/18
Filed: 1953-07-30
Abstract: 758,657. Anaesthetic apparatus. CYPRANE, Ltd. July 30, 1954 [July 30, 1953], No. 21165/53. Class 81(2). An anaesthetic vaporizing appliance has a main chamber for liquid anaesthetic, from which it is withdrawn into the vaporizing chamber, and a secondary chamber of space, into which the liquid passes if the device is inverted or tilted. The appliance is also provided with a filler which limits the quantity of liquid which can be placed in the main chamber. Liquid is poured in to level 35, Fig. 1, and passes through orifices 37, 40, 41, to a wick 23, where it is vaporized by air passing down a tube 8, through ducts 25 and up the outside of the wick to a temperature controlled valve member 29 on a bimetal strip 30. This mixes with air'received direct from a controllable air inlet 11 and passes out through a non-return valve 21 to outlet 22. If the appliance is tilted, the liquid passes into an upper chamber 4, clear of the wick. This chamber is normally vented through a nipple 42 to prevent liquid being forced out by temperature changes. The filler comprises a screwdown cover 50, Fig. 2, over an aperture leading to a channel 48 directed away from the anaesthetic reservoir. Normally the reservoir is filled with the device level, up to the filler orifice. However, it is impossible to add more than this if the filler is tilted upwards as the channel 48 fills and prevents it.
